@isiofran14 as Spock said,you do not choose to believe or not in a theory, IT IS FACT liked it or not.
Not believing in gravity doesn't mean you will float in the air when you jump off a building.
And the verse you just wrote has absolutely nothing to do with the Big Bang.
You still haven't made one simple or even partially factual statement.
Science started to develop only 400 or so years ago and look where we are already.
Not to mention the Scientists in this world are very few , even a rare commodity comparing to 7Billion people...
